Ok so I am running a 12 gallon DWC system and my babies are about 2 weeks into veg. I'm only about 4 nodes high and my babies don't seem to be taking off. I have been using fox farm big bloom liquid plant food only. I guess I am asking how much nutes I should be using in my solution and how often I should be adding nutes if any in my solution. Oh yeah and how often should I be changing my solution? Any help with this matter would be greatly appreciated. One more thing should I be using anymore nutes to feed my plants. You can clearly tell I'm a first timer.
